I just recently started wearing watches last june and have been going nuts ever since. in august i got myself a seamaster 120 2311.21 quartz and it is extremely accurate. Compared to my other previous quartz watches i've tried - Citizen, Casio and Swiss Army. The citizen was in the normal range of about 30 seconds per month. The Casio was a little bit worse and the Omega is coming in at about +1-2 seconds per week. I figure one minute a year or less, isn't bad. So i was wondering what the accuracy of some of your Omega watches are?
Are we talking Quartz watches? I have a non-atomic GShock that I set with the atomic clock at work. It's been months and months but it's still on time. I should go check it after the holidays to see how many seconds its off, but it's not a full minute off, I know though. My mechanical watches are always losing time (or gaining if I keep them wound). EDIT: checking against the atomic clock online my Casio Gshock is 15 seconds slow. I looked at my Amazon order date and it was 15 months ago. I don't see why i would have changed the time since, but it's possible that it was reset more recently and I can't remember.
My Speedmaster (several years old) seems to have settled on losing about 10 seconds a day. I generally set it a few minutes fast and then when it gets a few minutes behind I just bump the time up about once a month.
Your Speedmaster seems to be an automatic one, otherwise it is impossible to imagine such inaccuracy in quartz watches.
I have a speedmaster and a seamaster chronograph. The speedmaster needs winding, but the seamaster is kinetic. I've never checked the accuracy as they 'run out' because I don't wear them enough to keep them wound, or remember to wind them! I just set them to my iPhone when I put one on
I have a quartz Omega Seamaster Aqua Terra that was gifted to me. It is super accurate. I have a soft spot for autos, but I do appreciate the no fuss dead to nuts operation of a good quartz watch.
I lose about 6 seconds/ day on my Seamaster Professional 2531.80 but I haven't had it serviced since buying it new in jan 06. I consider that pretty good performance for an auto.
